THAWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,002, dated August 25, 181-35.

Application filed March 2, 1885.

To all whom it may concern.-

Be it known that I, FERDINAND L. MnNrEL, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Thawing-Machines, which improvement is fully set forth in the following specification and accompanying drawing, which is a side view, partly in section, of of my improved thawiiigmachine.

The present invention relates to my improvement in thawing-machines, consisting of a metal can or reservoir provided at its up per part with a steam or hot-water connection, and outwardly from the lower part a stop-cock having at its upper part a flexible tube connected therewith. The outer end of this flexible tubing is provided with a flexible metal tubing designed to be inserted within the frozen lead pipe, and by forcing hot water or steam through the said reservoir and tubing the ice within the pipe is thawed, and the water is thus removed by passing outwardly around the tubing inserted therein, all of which will now be set forth in detail.

In the accompanying drawing, A is a can or reservoir, having its upper part, B, formed, preferably, segmental, as shown in the drawing, and having the lower outer edge flanged to correspond with the upper part of the vertical sides, which is also flanged, the two being bolted securely together. The upper central part of this head or cap is provided with a suitable coupling device connected therewith, and stop-cock adapted to be connected with an air-pump. Immediately beneath the stop-cock G, I design to place a seat, D, to prevent the upward and outward passage of the air. Outwardly, at the lower part of the reservoir A, I provide a stop-cock, E, having upon its outer end a section of rubber or other flexible tubing, F, of any convenient length, and connected at its outer end I provide a section olsmall lead or other flexible metallic tubing, G, suitably coupled at a. This metallic tubing G is designed to be inserted within the (No model.)

pipe to be thawed, and is thus designed to be somewhat smaller than the pipe within which it is inserted, so that after the hot water or steam is forced into the frozen pipe the cold water escapes from the pipe by passing outwardly around the small metallic pipe. This metallic section G is also designed to be of any convenient length, s0 as to be pushed into and follow up the ice within the frozen pipe as it is thawed.

In operating the device I find it convenient to use either steam or hot water. In using hot water I first remove the stopcock O and fill the reservoir A with hot water, and then by means of air-pump connection force the said hot water through the stop-cock E and tubing F into the frozen pipe H, and as the ice is thawed I follow it up by pushing the flexible tubing into the said pipe H, and the waste water passes outwardly from the pipe H as fast as necessary.

Having described my invention, what I claim is- 1. In a t-hawingmachine, the metallic res ervoir having a segmental head at the top provided with a stop-cock connecting with an airpump, the lower part of the reservoir having outwardly a stop-cock having thereon a flexi ble tubing, the outer end of said tubing provided with a flexible metallic tube, substantially as herein set forth.

2. The combination of the metallic reservoir having a detachable flanged segmental head and coupling device, the lower part of said reservoir having outwardly a stopcock, with the flexible tubing, the outer metallic end to be inserted within the pipe to be thawed, substantially as herein set forth.

In testin'iony that I claim the foregoing I have hereunto set my hand, this 24th day of February, 1885, in the presence of witnesses.
